PV19 - pink and rose to crimson to violet
PB36 - turquoise and teal to greenish blue
PR101 - transparent burnt orange to granulating burnt orange to earthy red to very opaque earthy red
and
PBr7 - yellow earth to warm orange browns to dark orange browns to dark cool browns
- are some of the most schizophrenic!
Have a look at the PBr7 and PR101 section in this page of my website and you'll see what I mean. Some pigments cover a small range of colours, like PB29 Ultramarine, but others seem to cover a very large range not only of hue but also of characteristics. I'll look at PV19 here.
PV19 has a more rose version and a more violet version, though it also appears as a crimson (Alizarin Crimson Quinacridone by Da Vinci) and a dusky pink (rose Madder Permanent Hue by Art Spectrum.) Generally speaking, the more rose version will be called a Quinacridone rose/permanent rose colour where the more violet version will be called Quinacridone Violet or perhaps a magenta or mauve, but it does make it a little difficult to choose a colour based on pigments alone. As always, you need to look at the brand and the name to be sure of what you are getting.


















I love Quinacridone Rose as an excellent 'primary' red. It mixes beautiful purples with any blue, especially ultramarine, but also mixes pretty oranges and reds with a yellow. I find the Quinacridone Violet colour less useful as you can make a violet by adding a little blue to the rose, though you can't make a pink by starting with the violet.
The crimson hues made with PV19 are also useful to consider in a limited palette - Alizarin Crimson (quinacridone) by Da Vinci for example is a more crimson red, but still mixes nice purples and oranges.
Thanks for another very useful post on colour. It's a good reminder that all pigments aren't created equal!
ReplyDeleteThank you so much for all the wonderful posts!
ReplyDeleteI have a plastic palette with 18 slots lots of mixing space. I can also dot some colours that I do not need 1/2 pan for.
ReplyDeleteI have a hot press watercolour sketchbook made by Moleskin. Mostly pen/ pencil with colour washes is my plan to Florence Cinque Terre and Florence.You can tell by my question I am new to this.
**HELP** What 18 colours should I bring. I leave the 15th of Sept this year on my birthday.THANK YOU
Have a look at this page of my website and you'll see a Mijello palette set up with 18 colours. You can use this to paint anywhere. Happy travels. https://www.janeblundellart.com/palettes.html
DeleteHi Jane, I just wanted to double check whether the brand abbreviation ‘M.G’ stands for M Graham or Mission Gold. Many thanks :)
ReplyDeleteThank you so much! DS Quin Rose & Quin Violet (both PV19 on their tubes) were about to drive me nuts!
ReplyDeleteI didn't know if I could sub Q.Violet for Q.Rose in my "Cool/Warm" limited palette, but your statement, "you can't make a pink by starting with the violet" made it perfectly clear!).
Off to the store I go to get some Quin Rose! Lol
I’m fairly new to watercolor and have bought additional tubes here and just because I liked them in the store. Now I was looking and sure enough I have THREE that are labeled PV19 - Red Violet by Van Gogh, Permanent Rose by Cotman, and Phtalo Red by Grumbacher. Now that I know about pigments I’ll be more selective. And for what I paid for three lesser quality tubes bought on impulse I could have instead bought artist quality Daniel Smith. Lessons learned.
